Application led April 121917. Serial No. 166,555.

To all 'whom t may concern.'v Be it known that I, Grans ARDUSER, a.citizen of the United States, residing at (loggen,

in the county of Linn and State of Iowa, have invented certain new induseful IlnL provements in Tire-Shoes; and I do hereby declare thefollowing to be a. full, clear, and exact description of the invention,such as will enable others skilled in the art to which it apperteins tomake and use the same.

This invention relates to traction shoes for automobile tires, and hasfor its Object to produce :i shoe which may be att-ached -to e. tire inposition on .a wheel without jacking up the wheel, and when attached 1sadapted to aord erm and tenacious hold on the road, but without the jarincident to tires y y shod with chains or armor having radially by theseries of shoes is coupled to the chainv 4. Near this inner end the ermis provided with lateral studs 12, which serve to lock the shoe inposition on the tire, as will be expleined presently. The middle oftheshoe is provided with flanges 8,'- Whose opposite projecting teeth orspurs. Y

In the accompanying drawing, forming :i part of this Specification,Figure 1 is a. side view illustrating e portion of my improved shoe, asin use. F ig. 2 is a view of the same transverse Vto the tire. Fig. 3 isa view of the latching stirrup and the inner ends of the connectingradial arms ofthe shoe, the outer portion of the shoe not being shown 1nthis view.

In the drawing, the numeral 11 designates the rim, and 2 the tire of anordinary automobile wheel. Seated on the tire is a series of shoes '3,connected on one side of the wheel -by a chain li.V Considered singly,the shoe is formed with a. broad tread portion 5, which conforms to thecurvature of the tire. ThisA tread portion conforms to the outercurvature of a. segment of the tire, embracing, as to a cross-sectionofthe tire, and as shown in Fig. 2, -a little more than half of thecircumference. ItsV inner end is pierced, as shown in Fig. 1, to receivea link 7 whereedges ere practically periillel, the other i edges beingpractically et right angles thereto, and Bush with the tread of theshoe. These flanges therefore hear hut little, or not at all on thesurface of n hard street, hut the side flanges serve as traction wingsin mud or send.

To the side of the shoe opposite the radial arm 6 is hinged anotherradial arm 9, the hinge Ibeing shown at 10, Fig. 2. To the outer end ofthis arm is riveted e stirrup Il, of some slightly elastic ma.- terial,such as spring steel. Neer the outwardly turned ends of the stirrup-legsare holes 13, which register with the studs l2 above mentioned. The shoemay thus he secured in position on the tire by first turning heck thishinged arm to admit the tire, and finally he fastened in place byswinging the arm hack to the position shown in Fig. 2 and Fig; 3,-theperforated legs of the stirrup snapping over the studs. Even should theconnecting chain break, the shoes cannot es-V cape from their connectionwith the wheel. The construction also admits of the whole series ofshoes being attached to the wheel While restingvon the ground, inasmuches there is but one connecting chain, on but one side of the wheel, andthe individuel shoes may be separately opened and closed at will.Y 5

Having thus described my invention, I cla-im:

A tire-shoe, comprising' a. tread portion, an integral arm extendingradially inward from seid tread portion at one side, its end pierced toreceive a chain link, and having lateral, stirrup-engaging studs nearsaid end, and an arm hinged to the opposite side of the tread portion,and having :inelastic stirrup :it its free end to en age said studs. Intestimony whereof I a 'X my signature in presence of two witnesses. i
